My daughter has a 6 month old long haired weimaraner. He seems to be suffering form seperation distress. They have received complaints from next door that when they leave the dog starts barking, They have tried a collar that emits a sound when he barks but this has not worked. They have bought him a large crate which he is very happy in and uses himself when they are home. They have tried trial leaving, where they leave the house and come back after a short time and vary the return but this has not worked either. They have tried more exercise and walk him more than is recommended for his age. They cannot change his diet as he has a very sensitive stomach.
Any idea what else they can try?
Thanks
